PRINTING-PLATE-MOUNTINGr DEVICE.

Application letl December My invention relates to devices 'for servingas an accurate guide and, in addition,` as a temporary clamp inconnection with the mounting of printing plates in chases, mountingboards or blocks.

While my invention has a wider application, l have designed itparticularly tor use in making up a chase i'rom type plates 'forprinting manifolding forms.

1n such printing it is the general practice to print on a wide web ofpaper, two or more copies of a form, side by side, so that when thepaper is split along the dividing line between the form, there willresult two like printed slips which may be used in manifolding.

It is necessary in this form ci printing to have the two or more typeplates in a perfeet alignment and in case the alignment should becomedistorted 'for any reason to have a quick guide for setting the saidplates correctly in the chase again. llt is also necessary that thespacing of' the variou's lengthwise Vlines inV each plate shouldcorrespond.

1t is the object ot my invention to provide a device which can be usedin' connection with mounting boards or chases, and which not only servesas a guide to the press-man in arranging his plates in the chase, butalso holds the plates in the corrected alignment until the clampingblocks, nail 'fasteners, or the like in the chase may be completely andpermanently adjusted.

These objects and other advantages .to be noted 1 accomplish by thatcertain construction and arrangement of parts to be hereinafter morespeciiically pointed out and claimed.

l provide any sort of support 1, for my device, which may be a liat woodor metal structure having side bars 2, 2. rllhese side bars are formedwith 'lslots 3 for the clamping device, and lwith notched ribs 4 tor thestraight edge. The support will also have a shoulder or rib 5 againstwhich the chase may be set.

The straight edge comprises essentially a bar 6 having arranged along ita series of pointers 7 which are carefully positioned so as tocorrespond with some standard printing arrangement, such as in thisinstance, for a given vertical line of the sections of manitoldingpaper. This bar is adapted to seat in the notches of the ribs l and thusto be very accurately aligned across the bed.

@n one end of the straight edge bar is a small clamp 8, which straddlesthe rib, i. e. Slides upon it in any desired form of slider, and is heldon the bar by a screw so that it can be clamped down to the ribs on thesupport in desired position. This clamp may, of course, be duplicatedfor use on both ends of the straight edge. l have not shown it in detailas any form of device can be used or the device omitted altogether.

The clamp for holding a. chase down on the holder is constructed asfollows: Sta-ndards 9, 9, are provided having a brace rod 10 betweenthem, and T-headed' bolts 11 enin the 'l--slots of the support andpresenting` threaded ends for reception of clamping nuts 12.

Pivotally held in the standards is a rock shaft 13 having its ends 14keccentric to the body thereof, so that it acts as a cam.

rllhe tie bar or brace rod 10 carries arms 15, 15, which extend to apoint beneath the eccentrically mounted shaft. The arms 15 serve as thesupport for a mounting bar 16 and the arms are held rigidly on the rod10, so as to hold the bar 16 against movement.

rEhe clamp bar 17 has a series of pins'or posts 18V thereon, whichextend upwardly through the mounting bar, and have heads 19 lying in thepath oi' the eccentric shaft. Between the Vheads and the mounting barare springs 20, which bear against bar 16 and thrust up the pinsnormally to hold the clamp bar away from clamping' position. When,however, the shaft 13 is rocked by its handle 21 it will. contact withthe heads ot the pins and thrust them down, whereupon the clamp bar willmove to clamping position. v

As so constructed, the operation of the device is as follows; referencebeing had to a structure used with manitolding paper The press-manVarranges his printing` plates 22 in a chase 23, and thrusts the chaseinto the support until it abuts against the back shoulder thereoi". IIethen sets the straight edge piece which is designed Jfor his particularjob and adjusts the plates in the chase until they are in exactalignment transversely, and until the various vertical lines ot theseparate plates are in exact correspondence with the arrows Vor pointerson the straight edge.

He then thrusts down the handle of the eccentric shaft and clamps theplates and the chase as well into lined position, while he tightens upon the various blocks and hooks that move in the chase tor holding theprinting plates..

There will be no shitting of the plates during` the tightening'operation, due to the clamp, and any chance shift will be at once notedon the straightedge.

I have shown in Figure 3 an end view of a support l, which has legs l,and at one end a rack 24.-. This rack is provided to support a varietyof' straight edges, all of which are adapted lor use with the support,lout each of which has a diilerent pointer arrangement and has beenpai-tiem larly designed for one of the standard kinds ot work to bedone.

This multiplication ot straight edge pieces I tind of considerableeconomy ot time as against having adjustable pointers which would haveto be carefully set and subject to chance dislodgment.

I do not wish to be limited to the details of construction above setforth, and do not wish my failure to mention various equivalentstructures to be construed as a desire that my claims be limited inscope or application to the special form ot device selected tor purposeot illustration.

I-Iaving thus described my invention, what I claim as new and desire tosecure by lietters Patent, is:- n
